The pain eliminating effects of electroacupuncture have long been known however the analgesic mechanism involved has yet to be clarified. Recently with the discovery of endogenous analgesic peptids called endorphins much attention has been called to the relationship of these endorphins and the acupuncture analgesic effect. We examined to determine how electroacupuncture influences lumbar CSF endorphins and the so-called pain transmitting substance, Substance P.
In order to establish continuous lumbar anesthesia using tetracaine for 8 patients with gynecological lower abdominal diseases, a Tuohy needle was inserted from the lumbar area and a catheter inserted into the subarachnoidal space. In each case at the time of the insertion of the catheter 5ml. CSF was tapped. As pre-medication 0.01mg/kg. atropine sulfate, 2mg/kg secobarbiturate were administered. To maintain the analgesic effect hyperbaric or hypobaric tetracaine was administered according to individaul needs. For hypotension during the operations a plasma expander and when necessary ephedrine were administered by intramuscular or intravenous injection.
Immediately following the start of surgery acupuncture needles were inserted at right and left LI-4 and electrical stimulation at 3c/s, 1.0mA was administered for 50-120 minutes using the acupuncture therapy apparatus “TOKKI”. when the operation was finished, after 5ml. of CSF was again tapped through the catheter, the catheter was withdrawn as far as the subdural space and 20-40ml. physiological saline injected to combat the headache due to spinal fluid leakage. The test substance was immediately transferred to a siliconized test tube and cooled to a temperature of-80°C.
The RIA methods were used for the measurement of both endorphins and substance P. The crossover reaction between the β-endorphin and the βLPH was 50%. (Using the β-endorphin measuring kit manufactured by NEN).
The results in 7 of 8 examples showed a significant increase in CSF endorphins after electroacupuncture. It also became clear that there was a tendency for substance P levels to decrease due to electroacupuncture.

We report possibly the oldest patient in the world with both a ruptured abdominal aortic aneurysm and shock who was saved by accurate diagnosis and immediate treatment by trained medical teams specializing in emergency medicine, radiology, vascular surgery, anesthesiology, and internal medicine. The 96-year-old patient was transferred to our hospital because of sudden left lateral abdominal pain and hypotension that resulted in periods of unconsciousness and shock. An enhanced CT scan showed that the ruptured infrarenal abdominal aortic aneurysm was surrounded by hematoma that was located mainly in the left lateral abdomen, extended above the renal arteries (Fitzgerald type III), and was 7cm at its maximum diameter. Y-graft replacement was successfully performed after a rapid decrease in the patient's blood pressure was quickly restored by clamping the aortic neck by hand. Following the operation the patient developed ischemic colitis and cholecystitis, which were cured by conservative treatment. The patient was discharged 20 days after the operation. We were able to save this nonagenarian patient with both a ruptured abdominal aortic aneurysm and shock by immediate treatment provided by medical teams that are trained and coordinated.

BACKGROUND: The effectiveness of surveillance to identify extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-E) carriers is controversial during a non-outbreak situation. We performed additional stool cultures for ESBL-E among intensive care unit (ICU) patients already under active surveillance by means of sputum and urine cultures. We aimed to assess the efficacy of stool cultures for screening for ESBL-E in a non-outbreak situation. METHODS: We conducted a retrospective cohort study in an ICU. Sputum and urine samples were cultured for ESBL-E surveillance purposes from January to September 2013 (phase 1). Stool cultures were routinely performed in addition from January to September 2014 (phase 2). Antimicrobial use density values and clinical outcomes were investigated and compared between phase 1 and 2. RESULTS: We identified 512 and 478 patients in phase 1 and phase 2, respectively. ESBL-E were found in the feces of 65 (13.6%) patients in phase 2. The antimicrobial use density values (expressed as defined daily doses per 1,000 bed-days) were not significantly different between the two phases for fluoroquinolones (7 vs. 10, p = 0.376), third-generation cephalosporins (24.2 vs. 29.5, p = 0.724), tazobactam/piperacillin (44.6 vs. 57.3, p = 0.489), and carbapenems (73 vs. 55.5, p = 0.222). Moreover, there were no significant differences in ICU mortality and length of stay (11.5% vs. 9.8%, p = 0.412, and 9 vs. 10 days, p = 0.28, respectively). CONCLUSIONS: Stool culture seemed ineffective in improving the antimicrobial use density of broad-spectrum antimicrobials, clinical outcomes, and ICU length of stay, and is not recommended for surveillance of ESBL-E in a non-outbreak situation.

We report 3 cases of ascending aorta-abdominal aorta bypass for atypical coarctation with Takayasu's aortitis. We performed an extra-anatomical bypass from the ascending aorta to the terminal abdominal aorta. The graft was arranged to pass through the diaphragm from the pericardium, behind the left lobe of the liver and the stomach, to the front side of the pancreas to the terminal abdominal aorta. Although the graft was exposed in the abdominal cavity in part behind the stomach, it was completely covered with the great omentum thus avoiding direct contact between the graft the abdominal organs. Decrease in the pressure gradient between the ascending aorta and the abdominal aorta was achieved using a large prosthetic graft 14-16 mm in diameter. There are several advantages with this technique. (1) Positional change during surgery can be avoided. (2) Anastomosis can be performed in non-diseased vessels. (3) This bypass graft can be branched off to visceral arteries if necessary. Reduction of the after load on the left ventricle and long-term graft patency by using a large diameter prosthetic graft were anticipated. The postoperative courses of all cases were satisfactory. Case 1 died of another disease 11 years and 11 months postoperatively, but the graft to was still patent.

A 57-year-old man underwent subtotal graft replacement of the thoracic aorta for aneurysms of both the ascending and descending aorta. On the 20th post-operative day, pus was found to be draining from the sternotomy wound. The wound was opened and irrigated with 2% Povidoneiodine solution for a total of 3 months. Culture of the pus from the irrigation revealed Staphylococcus epidermidis. When there were no clinical indications of infection and wound cultures were negative, the necrotic sternum and surrounding tissue were debrided and an omental graft was placed in the cavity. Upon follow-up examination, the patient is doing well 10 months after the initial surgery.

Granulocyte-colony stimulating factor (G-CSF) is a naturally occurring glycoprotein that stimulates the proliferation and maturation of precursor cells in the bone marrow into fully differentiated neutrophils. Several reports of G-CSF-producing malignant tumors have been published, but scarcely any in the hepatobiliary system, such as in hepatocellular carcinoma (HCC). Here, we encountered a 69-yr-old man with a hepatic tumor who had received right hepatic resection. He showed leukocytosis of 25,450/microL along with elevated serum G-CSF. Histological examination of surgical samples demonstrated immunohistochemical staining for G-CSF, but not for G-CSF receptor. The patient survived without recurrence for four years, but ultimately passed away with multiple bone metastases. In light of the above, clinicians may consider G-CSF-producing HCC when encountering patients with leukocytosis and a hepatic tumor. More cases are needed to clarify the clinical picture of G-CSF-producing HCC.

The purpose of this case report was to report a rare case of pyogenic spondylodiscitis caused by Campylobacter fetus. A 37-year-old male presented with fever and low back pain. By lumbar magnetic resonance imaging (MRI), no abnormal finding was observed at the first presentation. However, low back pain was aggravated, and fever did not improve. Thus, lumbar MRI was repeated on the 26 day after the onset of symptoms, showing abnormal signals at vertebrae and disc spaces, and pyogenic spondylitis was diagnosed. The possibility of pyogenic spondylodiscitis should be taken into account if a patient presents with low back pain and fever, and areas of low signal intensity on a T1-weighted MRI should be carefully examined. When initial MRI does not reveal abnormal findings, repeated MRI after one or two weeks or, more favorably, immediate gadolinium enhancement MRI, are important for patients who have persistent low back pain and fever.

A 64-year-old man was found to have a nodule in his right lung. He also complained of nausea and abdominal pain during the clinical course. Esophagogastroduodenoscopy revealed a duodenal ulcer associated with severe stenosis and a suspicion of malignancy. However, three subsequent biopsies revealed no evidence of malignancy. The fourth biopsy showed scattered large eosinophilic cells with an eccentric nucleus, leading to a diagnosis of Russell body duodenitis (RBD). RBD is an extremely rare disease, and little is known about its etiology and clinical course. The pathogenesis of RBD is discussed based on our experience with this case.
